RU-435TH A/B—35 A Shore is a brushable mix that cures to a soft, elastic rubber. This liquid rubber is excellent for making brush-on molds. Silpak RU-435TH consists of two parts (A and B) that immediately thicken to a brushable or trowellable consistency after mixing. Once cured, this urethane RTV provides a strong, durable mold with excellent, high tear resistance and good elongation. This non-sag product is especially useful for application to vertical or overhead surfaces. The rubber molds are suitable for casting plaster, concrete and waxes, as well as limited casting with polyester, epoxy and polyurethane resins. Since RU-435TH bonds well to many surfaces, it can also be used as an adhesive and a sealant.
